Specification of LettrsPatent,

Application filed September a, 1917, Serial No; 190,362.' Renewed September 5', 1918. seam. 252,790.

f To allwhom it may concern: a 1

Be it knownthat I, ,LUKASzjKRAWIno, a sub ect ofthe Emperor of Austria, residing. at Pittsburgh, in the countyof Allegheny and State of Pennsylvania, have invented,

' certain new and. useful Improvements in Package Handling Devices, of-whichthe following is a specification.

. This invention relates topackage handling: devlces and has special reference to a. de-* vice for use inloading and'unload-ing freight and baggage cars, the device being" constructed for the purpose 5 of handling With easethe packages such as tru'nks,- boxes,

bales,'and .the likebothiin loading. the cars and in unloading the: same. i g

I One important object Ofz thfi invention is to improve andvs'implify' the general construction of devices ofthis character; .1 j o A second impo rtantaohjectoof the invention is to provide a device of: this character which is of novel, construction and is so ar-i ranged that a minimum of labor is required in handling packages even though they may be very heavy and clumsy.

A third important: object of the invention is to provide an improvedfdevice of this character which, includes a traveling package carrieriarrangedto run along from one end to the other ofa train platform; the dev ce also including car supported; P

receiving elements so arranged that they may lower the desired packages from the traveler to the carfioor in the process of loading and in the process ofiunloadingi lift the packages from "thecar floor level 0nto thetravelingcarrier.-. i v

A fourth importantobject of the lnven tioniis to provide an improveddeviceof this description wherein what maybe t'ermed the elevating devices 4 are so arranged that they: may lift cer'tainsielected packages off I I tion the general. arrangement is shown if! claimed? p In the accompanying di va wing;:like"char-'- actersof; reference indicate, like I parts the Fig. to show thejdrivirig ofthe crane.

7 In generalflthe. invention. consistsof. a

traveling carrier "arrangedinfixed relation to a crane truss on bridge; the latter -m0v-,; mg over an elevated cranerunway. of the ordinary type fromone side of train 7 platform and tracks to ithelother side there ofii y Inconnection:- with this traveling; care rier the supporting part of which consists of certain fingers there are positioned within the car certain' i'elevating;devices so arranged that 'whenfatrain is on aitrack along-J sideofthe platform these devices will come ,8 is a section onathe linje beneath the'crane runway; These elevating,

devices also have their-supporting;surfaces consist ng of fingers: and the fingers of the oftheicarrierin the upward and downward movement offthe' elevating device so -that after-the carrier, isrpositioneda' over an elevating-deviceupward movement 0f the lat 'ter will lift any packages Zdesired u wardoft of the; carrier. r

' In: th'eipresent' embodi of; the inven- Fi'g. wherein there; is disclosed a platforni lOhaVing at one side thereof railroad tracks 11 whereon run cars indicated at 12. Sup-1 ported; on suitable columns 113 is' runway elevating device pass between -t11e :fingers securedthe u per" and inner-yends of finger '7 outwardly, as at 20 to extend f laterally tov Ward:the sides'of thecrane runway, theex o o tremitieseofwtheseis-finger' bars being indi Y means as for instance the motor 27 andcatcd at 21. These finger bars are held in position by suitable braces 22 and are connected 1n spacedrelatlon by an I-bos's 23. Moreover, the curved portions 20 of the finger bars are held apart by braces 24. It

is to be noted that the, portions 21 of the finger bars lie slightly above :the level .of

the car top. 1 H

This crane with its attachments constitutes the traveling carrier on Y which the packages are placed fordistributionto the various cars and this carrier-is caused to.

traverse the'cran'e runway bymeans of suitable gearing connected to one of the wheels 16 and which is here shown at 23, one of the gears being carried on the shaft 26. This shaft 26' is revolved by any desired gear 28- but it is to be observedfthat I do not confine myself to a motor'and gear for rying a sprocketwheel 33 all of the sprocket wheels being connectedtogether to'revolve in unison by a chain 34. One post 29 is provided with a gear 35 wherewith meshes a gear 36 carried on a shaft 37 capable of be ing revolved by gearing 38 so that the operator by revolving the gearing 38 causes revolution of all of the posts 29 and thus raises or lowers the frame 31. V I I Supported above the frame-31 by suitable braces 40 are finger bars 41 these finger bars being of such dimensions and so arranged that when the traveling carrier stops centrally over an elevating device the finger bars 11 will lie below and between the finger bars 21 so that operation of the gearing 38 will raise the finger bars 41 upward between the finger bars 21 and thus lift ofi' the latter any package which maybe resting thereon. The mo'vement is reversed after thecar has'moved away from' beneath the crane runway so that the finger bars 41 may attain the lowest position within the car.

At onesideof each of the car carried devices is aconveyenbelt42 one ofthepulleys of which is located on the shaft 37 and" adj 'acent this conveyor belt is ailoa ding incline or chute-43. Ii -order to operate the gearing 38 one of the'gears is supported on a shaft i 44 which is connected by suitable sprockets and a chain 15 with an engine indicated in general at 46 the engine being of any desired f type and: it being "obvious that an electric motorl may replace the engine. Furthermore, in order to permit the passage of the carrying frames upward through the car a suitable hatchway 417 is provided having supported thereabove a sliding door 4C8 which may be closed when desired to protect the car from the weather. From the foregoing it will be seen that packages may be placed on one-half of a car supported frame and the crane supported frame placed in such position, with othcrpackages thereon, that the car may be run past the station without stopping. Thus the upwardly curved portions of-the finger bars will effect transferal of packages on the finger bars from one frame to the other.

There has thus been provided a simple and efiicient device of the kind described and for the purpose specified.

It is obvious that many minorchanges may be made in the form and construction of the'invention without departing from the material principles thereof. It is not there' fore desired toconfine the invention to the exact form herein shown and described but it is wished to include all such asproperly come withinthe scope claimed.

Having thus described the invention, what is claimed as new,is: V

1. The combination with an overhead traveling crane; of a package carriersupported by said crane, and car supportedelevating devices positioned below the path of travel of said carrier and movable vertically to lift packages off of said carrier. 1

2. The combination with an overhead traveling crane; of a package. carrier supported by sald crane and including a plurality of spaced laterally extending fingers, a car supported elevating device positioned below the'path of travel of said fingers and including a plurality of spaced laterally ex tending fingers arranged to lie'intermediate the fingers ofthe-carrier, and means to move the fingers of the elevating device vertically through the spaces between the fingers of the carrier. I

3. The combination with an overhead 'traveling'crane; of a package carrier-supported by said crane and including aplurallty ofspaced laterally'extending fingers, a

.car supported elevating device positioned below the path of travel of said-fingers and including a plurality of spaced laterally extending fingers arranged to lie intermediate the fingers'of the'carrier, said elevating device also including a supporting frame, nuts earned by the supporting frame, screw posts passing through said nuts, and means on the frame to rotate an of the posts simultaneously:

4:. The combination with an overhead travehngcrane; of a package carrier supported by said crane and including a plural-- ity of spaced laterally extending fingers, a

car supported device positioned below the path of travel of said fingers and including a plurality of spaced laterally extending fingers arranged to lie intermediate the fingers of the carrier, said elevating device also including a supportingframe, nuts carried by the supporting frame, screw posts passing through said nuts, sprockets on said.

posts, a sprocket chain connecting all of said sprockets, operating means, and gearing connecting the operating means and one of said posts.

5. The combination with a train platform having tracks at the side thereof and a crane runway extending thereacross, of a traveling crane on said runway, a package carrier supported by the crane and having package supporting fingers extending laterally in a plane above the stop of a car on one of said tracks, and a car supported elevating device including fingers normally below the firstnientioned fingers and arranged to pass vertically therebetween, said elevating device being arranged to lift'packages off the carrier and transfer car fioor.

In testimony whereof I aflix my signature.
